Calculator guide
Calculate a gratuity and split the bill evenly among a group.
Formula or method
Tip = bill × tip rate; total = bill + tip; per person = total ÷ party size.
How to use this calculator
- Enter the pre-tip bill.
- Choose a tip percentage and party size.
- Review the tip, total, and per-person share; round according to local practice.
Worked example
For a $84 bill, 18% tip is $84×.18=$15.12, the total is $99.12, and four people owe $24.78 each.
Understanding the result
The result is arithmetic guidance; local customs, service charges, and taxes may change what is appropriate.
Limitations and assumptions
- Does not decide whether a service charge already includes gratuity.
- Splitting evenly may not fit different orders or separate checks.
